Interspecific brood parasitism occurs when the eggs of one species are laid in the nest of a different species, but evidence of this phenomenon is scarce. Facultative interspecific brood parasitism has been described in Charadriiformes. However, to o

We present current data on the occurrence of four Soricomorpha and 15 Rodentia species. The mammals were collected during trapping of common shrews and yellow-necked mice for chromosomal research and the common hamsters for phylogeography and genetic

Given the many detailed studies on the breeding biology of gulls, surprisingly little is known about conspecific brood parasitism (CBP) in these birds. CBP has been recorded in only a few of the roughly 60 species of Laridae. We studied CBP in two co

Somatic chromosomes of 17 northern birch mice, Sicista betulina, originating from lowland and Tatra Mountain populations were studied. In the whole studied material constant diploid number of chromosomes (2n = 32) was found. Polymorphism of a pair of

Common shrews display two types of Robertsonian (Rb) heterozygosity: simple (where CIII configurations are formed at meiosis I) and complex (which have longer meiotic chains or rings). Based on an analysis of large sample sizes (over 100) of MII cell

A whole-arm reciprocal translocation (WART) between the metacentric chromosomes af and hk is described for a single hybrid between chromosome races Drnholec and Łegucki Młyn. This translocation resulted in the metacentric chromosomes ah and fk, pre

In Central Poland, two similar chromosome races of the common shrewSorex araneus Linnaeus, 1758 were earlier described: Drnholec race (arm combinationsgm, hi, ko, nr) and Stobnica race (gm, hi, ko, np). Great similarity in size and G-banding patterns
